BEEN ACTING LIKE IT DOESNT HAVE ANY POWER. I HAVE CHANGED THE MAF SENSOR,TPS, AND IDLE AIR CONTROL. WHEN YOU TAKE OFF IT SEEMS LIKE IT WAS IN OVERDRIVE LIKE GEAR IT WILL MOVE BUT YOU PRESS ON THE GAS AND IT DOESNT REALLY MOVE ANY FASTER THE ONLY WAY IT WILL GO FASTER IF YOU FLOOR IT SO THE PASSING GEAR KICKS IN. IT DOES THIS ON FIRST AND SECOND GEAR. BUT YOU CAN DEFINETLY FEEL THE LACK OF POWER ON THE HIGHWAY ALSO. I HAVE TAKEN IT TO TWO SHOPS TH EFIRST IS A VERY GOOD TRANSMISSION SHOP CAUSE I THOUGHT THAT IT WAS THE TRANS BUT HE CHECK IT AND SAID IT DEFENITLY WAS NOT A TRANS ISSUE CHECKED FUEL PRESSURE SCANED THE COMPUTER NO CODES BUT HE TOOK OFF MAF CLEANED IT AND IT GOT FIXED BUT AFTER A FEW DAYS STARTED DOING IT AGAIN. SO I PUT A NEW ONE FROM AUTOZONE AND NO CHANGE SAME THING. SO THREE MONTHS LATER A TOOK TO ANOTHER SHOP AGAIN NO CODES BUT HE SAID SINCE I BOUGHT THE SENSOR FROM AUTOZONE HE SAID HE WOULD RECOMEND I PURCHASE FROM SOMEWHERE ELSE CAUSE AUTOZONE PRODUCTS ARE FAULTY SO I WHENT TO GO EXCHANGE IT AT AUTOZONE AND I PUT A NEW ONE SAME THING. SO TODAY I WHENT TO THE SALVAGE YARD AND PUT IT ON AND SAME THING. SO KNOW AFTER PAYING $100 TO EACH SHOP TO TELL ME ITS THE MAF SENSOR STILL NOTHING WHEN IT WORKS NORMAL GIVES ME 20 MILES PERGALLON WHEN NOT WORKING GOOD IT GIVES ME 14 MILES PERGALLON SO THIS TELLS ME IS SOMETHING WITH AIR FUEL MIXING PLEASE HELP DONT KNOW WHAT TO DO ANY MORE.
